"Derrik removed a fair amount of sand box sand that i was having a hard time disposing of, then dug out 5 cement footing to our old playground and finally leveled and landscaped a section of our back yard. I couldn't be more pleased with his work. He even discounted his original estimate because we did not need top soil and I and my neighbor assisted ( if you want to call it that) some of the raking. I highly recommend Derrick and Northen Edge phil and beth"

Excavating questions, answered by experts

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

Hard soil could be a sign of overly dry dirt, either from poor drainage or drought. It's important to test the nutrient levels, density, and drainage capacity of your soil to see if it's absorbing water properly. Begin by adding a light layer of water and observing how long the soil retains moisture. If you experience a good deal of runoff, you may need to aerate your lawn, apply a wetting agent, or hire a professional for a closer look.

It is a common belief that excavation is easier or less costly when done in the summer or when the ground is not frozen. Seasons have little effect on when excavation can occur; however, inclement weather can prolong the duration of the job and potentially increase costs. For this reason, those in rainy climates may opt for seasons with milder weather.

The rules and regulations regarding groundwater use vary between states. To find out if you can dig a well on your property, you’ll have to consult these regulations, address any compliance requirements, and get the appropriate permits. It’s also important to check that your intended location has the right geology and water table to support a well.

This depends on your location. Sewer lines can be buried anywhere from 18 inches to 8 feet deep. People in colder climates will have deeper sewer lines than people in warmer climates due to the dangers of the frost line and freezing pipes. Permits are required for all aspects of septic system installation, so the city should have the building plans for your system, which will tell you how deep your lines are.
